According to CoinMeta, Wu said that pumpfun announced the launch of holder and rewards, and canceled cashback as an option for new token issuance. Thereafter, creators can choose between the standard creator and fee tokens, as well as the existing cashback and creator tokens, which can also be applied to convert into holder and rewards. However, the conversion is irreversible. The fees generated from holder and rewards tokens will go into the pumpfun distribution wallet and are automatically allocated multiple times per hour based on the proportion of holdings. Users holding tokens worth over $20 can receive rewards, which are paid in the form of tokens from the trading pair. The SOL / USDC trading pair continues to use a tiered fee structure that decreases as market value rises, while for custom and pairs, creators can set a fixed fee rate of 0.01% to 3% at one time, and this rate cannot be changed after setting.
